Slipknot frontman Corey Taylor recently gave further details on Dave Grohl's upcoming Sound City Studios documentary and confirmed that their recent collaboration was part of the project.

Dave Grohl hasn't volunteered much information about his upcoming documentary involving the studio where 'Nevermind' was recorded --the now closed Sound City Studios. The one thing Dave has hinted at is that we can "expect some epic jam sessions." Those "epic jam sessions" will presumably involve the artists he has recently been working with -- members of Ratt, Cheap Trick, REO Speedwagon and -- the most recently revealed co-conspirator -- Slipknot vocalist Corey Taylor.

Most of the information we have on the upcoming documentary has come from the other parties involved with the project, not Grohl.  The most detailed description to date came from Corey Taylor's recent conversation with Artisan News:

"[Dave is] doing a documentary about the legendary board from Sound City that everybody and their mom recorded on — everybody from [Nirvana's] 'Nevermind' to, actually, [Slipknot's] 'Iowa'," Corey said. "And he's slowly but surely gotten all these people together to make music on that board again. And he called me. He was like, 'Would you like to do a tune?' I was like, 'Are you serious? I'm on a plane right now.' And it's really cool, because it's me, Dave and Rick Nielsen [Cheap Trick] on one tune. And I'm like, 'Ahh…. Excuse me?!' It's just a huge check mark on my bucket list, let's put it that way. And I'm really ecstatic. It's a really good tune."

There is still no official word as to when the upcoming documentary (and possible soundtrack) will be available but based solely on the "jam session" aspect of the project -- we will most likely see it at some point in 2012.
